SEMI-METALLOCENE CONTAINING CATALYST COMPOSITIONS AND POLYMERISATION PRODUCTS OBTAINED USING SAME Russian patent published in 2014 - IPC C08F4/6592 B01J31/22 C08F10/00 C07F17/00 C07F7/28 C07F7/00 

FIELD: chemistry.

SUBSTANCE: disclosed are polymerisation catalyst compositions which contain a product of contacting a hybrid semi-metallocene compound with a ligand which contains a heteroatom bonded with a transition metal atom with an activator. The invention also discloses method for polymerisation of an olefin in the presence of said catalyst composition and novel compounds which are part of a catalyst system. The metallocene compound has the formula: , where: M is Zr, Hf or Ti; X¹ and X² are independently a halide or a substituted or unsubstituted aliphatic, aromatic or cyclic group, or a combination thereof; X is a substituted or unsubstituted cyclopentadieneyl, indenyl or fluorenyl; X⁴ is -O-R^A, -NH-R^A, -PH-R^A, -S-R^A, or -CR^B=NR^C, where R^A, R^B and R^C are given in the claim. The activator is a substrate activator containing a solid-phase oxide treated with an electron-acceptor anion. The novel compounds have the formula: indenyl(X⁴)Zr(CH₂phenyl)₂; where X⁴ is

; or .

EFFECT: polymer has a wide molecular weight distribution similar to that of resins obtained using ordinary chromium oxide-based catalysts.
